As above, they are jeep Cherokee boxes. I stumbled on a you tube vid about them and thought they looked spot on. I have de-wired a lot if the terminals but it's a pain in the arse. Ideally I would like new connectors but I can't find them anywhere. Probably best just to use the pig tails.

You made a really nice mock drawing of your fuel system! Have you installed everything yet? If so how did it go?

It's all in but I haven't run fuel through it yet.

I ended up having to change some of the connectors at the FPR to get the pipe angles I wanted. The only problem I have now is that the fuel pipe comes up by the bulkhead right where the heater pipes are so I need to bend the hardline.

1 - horn is on as soon as you attach the battery - spent a while looking at this but I can't see why it isn't working. They are aftermarket horns so maybe I have to wire them differently?2 - wiper motor doesn't work - this is getting on my nerves. I have power at the fuse, and motor socket but still no go.I can't believe the motor has failed since I last fitted the loom3 - Sunroof doesn't work - sorted. I missed a couple of plugs4 - Electric mirrors don't work - sorted. I missed a couple of plugs5 - Heater blower doesn't work - Now this works to a point. It comes on but pulses on - off - on off, a bit like and indicator. No idea what's happening there.6 - Windscreen washer motor doesn't work - sorted. I missed a couple of plugs

The only things I've changed since everything last worked was to remove the circuit relay as only one wire was attached to it (apart from the wire that goes to the EGI relay).

The blower's electrical system in the FD is pretty dead simple. You can read the diagram on Z68 of your FSM bible. It consists of a relay, fuse, resistor, position switch, and the actual blower motor. The relay turns on with switched power from the ignition switch. I wouldn't point my finger at the ignition switch otherwise, a lot of other things would be pulsing in the car. The relay could have a bad ground, but your pulses would be accompanied by an audible relay click. Easy to check. Ground for the blower resistor is right below the passenger A pillar. The fuse shouldn't be an issue. The resistor could be an issue as it's the #1 thing to fail in the system, just from my observations of people PMing me and working problems down to the resistor, however, I've never heard of a case that would pulse the motor as the resistor is just a chunk of metal and ceramic and can't change its resistance on the fly unless it's got some kind of crazy thermal runaway thing going on. I suppose the motor could possibly be broken enough to pulse. I'm not sure how the FD's blower motor is constructed, nor am I a motor expert, but I would imagine it's just a simple DC brush motor. I haven't heard of brushes needing to be replaced on the blower motor, but perhaps that could cause the issue? The position switch is simple/mechanical. I don't see how that could pulse the motor. Finally you have the blower motors ground, which could be improperly grounded. It's in the passenger kick panel.

Hope that helpsLane

Thanks for the input Lane. I found out what the problem is and I am a little ashamed. I noticed that when I touched certain electrical connectors the fan worked fine but it was eratic. After a while I noticed that the dash support was earthing on the gear stick. When I leant over the dash to touch the connectors I broke the earth contact
